RAIL-TIE.

Specification of Letters Patent.

' the same. a

This invention relates to rail ties of the channeled metallic type, and having wooden. seats for the rails, one object of the invention being to improve the construction of the tie by so forming the lower wall thereof that the tie will be prevented from sinking in the road bedbeyond a certain point.

Another object of the invention is toadmit of any water that enters the interior of the tie escaping past the wooden blocks that form seats for the companion rails.

,IOther' objects will appear and be better understood from that embodiment of my invention of which the following is a specification, reference being had to the accompanying drawing forming a part thereof, in which:

Figure 1 is a top plan view of the rail tie constructed in accordance with my invention, showing the manner of securing one of the-'rails of. the track in operative position thereon, I

Fig. 2 is a side elevation of the tie, partly in section,

Fig. 3 is an end view of the tie, and

Fig. 4 is a transverse section, taken through one end of the tie.

Referring to the drawing in detail, the tie is shown asv consisting of a channeled elongated body, having a lower or bottom wall 1 and opposite side walls 2, the lower wall 1 being of a greater thickness than the side walls 2, so as to give the lower wall maximum strength, and the side walls 2 are gradually increased in thickness toward thelr lower edges so as to reinforce the points of juncture between the side walls and the in lll lower wall of the tie. The under surface of the lower wall 1 of the tie is provided with a longitudinal groove 3, that is of arcuate shape in-cross section.- By so forming the lower wall of the tie with the grohve 3 the material of which the road bed is formed,

will fill the groove or concavity3 and serve to reduce, to a considerable extent, the sinklng of the tie in the road bed.

The opposite ends of the side walls of the tie body are reduced and the upper edges of the opposite ends of the side walls are formed to provide recesses l. The recesses 4: on one side wall register with the recesses 4: on the opposite side wall and provide passages for the base flanges of the rails of the track, as shown more particularly in Fig. 4: of the drawing. Each side wall is cut away adjacent the recesses at to provide opposed downwardly inclined surfaces 5, and shoulders 6, for a purpose to be hereinafter explained.

Positioned within the tie, and at the opposite ends thereof, are wooden blocks 7 which have their upper surfaces lying above the planes of the lower walls of the recesses 4:, and formed with seats for the rails, designated 8. The undersides of the blocks 7 are provided with longitudinal grooves 9, which admit of the water that enters the interior of the tie body escaping therefrom.

/ Companion rail clamps 10 are located, re-

spectively, on opposite sides of each of the rails 8 of the track and rest on the inclined surfaces 5 formed in the sides of the tie, and each is provided with a horizontal extension 11, which overlies the upper side of the adjacent block 7 and is secured thereto by means of a bolt 12, which passes through the lower wall 1 of the tie and through the block 7 and the extension 11, and has its upper end threaded for the reception of a nut 13, which'is adjustable against the upper side of the extension 11 ,so as to hold the bolt in operative position. The outer edges of the rail clamping members 10 engage against the shoulders 6, so that any lateral strain or any lateral force exerted on the clamping members 10 by the adjacent rails will be prevented from being distributed to the fastening bolts 12. i

It is evident that various changes might be resorted to in the construction, form'and.

arrangement of the several parts without departing from the spirit and scope of the invention; hence I do not wish to limitimyself strictly to the structure herein described.
